在请求时不排序表头的方法取决于你使用的编程语言和框架。下面是一些常见的编程语言和框架的示例：

1. Python（使用requests库）：

import requests

headers = {
    'X-Header': 'value',
    'Content-Type': 'application/json',
}

url = 'https://example.com/api'
params = {'key1': 'value1', 'key2': 'value2'}

response = requests.get(url, headers=headers, params=params)

2. JavaScript（使用fetch API）：

const url = 'https://example.com/api';
const headers = new Headers({
  'X-Header': 'value',
  'Content-Type': 'application/json'
});
const params = new URLSearchParams({
  key1: 'value1',
  key2: 'value2'
});

fetch(`${url}?${params.toString()}`, {
  method: 'GET',
  headers: headers,
});

3. Java（使用OkHttp库）：

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

public class Main {
    public static void main(String[] args) {
        OkHttpClient client = new OkHttpClient();
        String url = "https://example.com/api";
        Map headers = new HashMap<>();
        headers.put("X-Header", "value");
        headers.put("Content-Type", "application/json");
        Map params = new HashMap<>();
        params.put("key1", "value1");
        params.put("key2", "value2");

        Request.Builder requestBuilder = new Request.Builder()
                .url(url);

        for (Map.Entry entry : headers.entrySet()) {
            requestBuilder.addHeader(entry.getKey(), entry.getValue());
        }

        HttpUrl.Builder urlBuilder = HttpUrl.parse(url).newBuilder();
        for (Map.Entry entry : params.entrySet()) {
            urlBuilder.addQueryParameter(entry.getKey(), entry.getValue());
        }
        String completeUrl = urlBuilder.build().toString();
        requestBuilder.url(completeUrl);

        Request request = requestBuilder.build();

        try {
            Response response = client.newCall(request).execute();
            // 处理响应
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请注意，以上示例仅为示范。根据你使用的编程语言和框架，代码可能会有所不同。请根据你的具体需求进行适当的修改。
